Grandstream GVR3550 is a high‑performance standalone NVR designed for small to medium businesses that need robust, feature‑rich surveillance without the cost and complexity of enterprise‑grade servers. It offers the perfect balance of channel capacity, storage flexibility, and data protection – all in a compact, user‑friendly appliance.
Flexible Recording Strategy: The GVR3550 supports up to 24 camera streams simultaneously, automatically adjusting recording parameters to match each camera's resolution and bitrate. You can mix 720p, 1080p, and lower‑resolution cameras without hitting performance bottlenecks. Continuous recording, motion‑triggered snapshots, and custom schedules give you granular control.
Data Safety Built‑In: Unlike basic NVRs, the GVR3550 offers RAID 1 mirroring across two of its four drive bays, so even if a hard disk fails, your video evidence remains intact. The hot‑swappable drive bay design makes maintenance quick and simple.
Comprehensive Connectivity: HDMI and VGA outputs allow direct connection to monitors or TVs for live monitoring – no separate PC required. Four alarm input terminals and a relay output integrate the NVR with door sensors, panic buttons, or external sirens. USB and eSATA ports enable fast video export and backup.
Unified Grandstream Experience: The GVR3550 is part of the Grandstream ecosystem. It auto‑discovers Grandstream GSC series cameras, reducing setup time to minutes. It can be managed via the same GDMS cloud platform as your Grandstream phones and access points, giving you a single‑pane‑of‑glass view of your entire IT infrastructure.
